"fresh" and "built" engine definitions

[barryogen]

ok, I've been reading and reading, and I don't know the difference between a "fresh" and a "built" engine, or what either of them really mean.

it seems that a fresh engine is one that has had things put back to stock levels with new gear(pistons/rings/bearings and maybe other things)?

and a "built engine" is one that has had things changed a bit to take a bit more punishment?

Do these sound correct? and if not, can someone tell me what they really mean?

they are only really slang terms anyway, everybodys interpretation could be different.

fresh to me means rebuilt to standard spec with standard parts, not neccessarily replacing all parts but ensuring all parts are within factory tolerances etc. basically a new engine with next to no km's on it or just run in.

built to me means eactly that, built for a purpose. there would be hundreds of possibilities for a built engine, depending on what puropse the engine is to be used for, but my understanding would be that the duties of the engine would be beyond the limit of standard parts.

what about a "freshly built" engine
you may as well ask how long is a piece of string

[barryogen]

yeah, thats what I thought... they just seemed to be terms used with no qualification as to what they meant.

In the States, 'built' seems to mean anything that has major modifications - aftermarket intenals etc. You hear it on US car vids a lot.

yep, I'm reading US forums... and "built" seems to be used in reference to pretty much anything that is adding 50% more HP than stock, but they usually say things like, "if you are going to do that, you're going to need to get a built motor" with no reference to what that means...

Although, from what yanky sites seem to sell as a built motor, it seems to suggest...

fully assembled block with rotating assembly consisting of cylinder sleeves, pistons, connecting rods and new crankshaft, with all associated bits(rings bearings etc) replaced.

Freshened to me means the bits that wear out - rings, bearings, seals etc have been replaced but the original parts they are attached to eg pistons, conrods etc haven't been changed. I see rebuilt as having the pistons, conrods and maybe crank changed and possibly a rebore as well.

When yanks say built it tends to mean forged internals etc.

Yup built motor is a very non standard engine block and head.
